Steel ball measuring table

Abstract

The invention discloses a steel ball measuring table. The steel ball measuring table comprises a pedestal, a working table and a detection arm member. A plurality of detection stations used for placing steel balls are arranged on the working table. The detection arm member comprises a support arm and a detection sliding base arranged on the support arm in a sliding manner. A displacement sensor is arranged at the end part of the detection sliding base. The detection sliding base is equipped with an elevating driving device and an adjustment device. During detection, a reference steel ball is placed in a detection station, the detection sliding base is moved downwards, thus the displacement sensor is pressed against the reference steel ball, the adjustment device is adjusted to limit the downward movement height of the detection sliding base, at this moment, the displacement sensor records the reference displacement value, the detection sliding base is lifted, a steel ball to be detected is placed in a detection station, the detection sliding base is moved downwards to the height limited by the adjustment device, and at this moment, the difference between the value of the displacement sensor and the reference displacement value is the error of the steel ball diameter. The detection precision and the detection speed can be raised greatly after the high-precision displacement sensor is employed, operation of professionals is not needed, and detection is convenient and fast.

Description

technical field [0001] The invention relates to the field of steel ball manufacturing, in particular to a steel ball measuring platform. Background technique [0002] In the production of steel balls, the inspection of steel balls is particularly important. The radius error and surface defects of steel balls have a great impact on the application of steel balls in the later stage. The traditional inspection method is to directly detect through a micrometer, which is very inaccurate , and the experience of the testing personnel is very high, and its detection accuracy usually can only reach 1 μm, especially when detecting miniature steel balls, the detection accuracy cannot meet the detection requirements. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a steel ball measuring table, which has the advantages of high detection accuracy and convenient detection operation. [0004] The technical solution adopted...
